Should I Stay or Should I Go? Migrating Away from an Incumbent Platform
Incumbents enjoy competitive advantages over new entrants, because users hesitate to abandon a widely-used platform for one with few users. A new model explores factors that increase and reduce incumbency advantage.
Policymakers should examine practices that deter multi-homing.
The Value of Incumbency When Platforms Face Heterogeneous Customers
Policymakers are unsure how much competition between platforms like Microsoft or Apple is possible or desirable. Consumers are reluctant to switch platforms, giving incumbent firms an advantage.
Competition between platforms benefits consumers. Incumbents may earn less profits than predicted.
Incumbent digital platforms may enjoy advantages over new entrants. Factors affecting the extent of the incumbent’s advantage include consumer coordination problems and consumers’ ability to join more than one platform.
Regulators can reduce some incumbent advantages by requiring access to data.
This paper asks how consumers’ costs and choices affect competition.
Competition means that consumers switch between products. Economists have argued that competition will suffer if consumers find it hard to switch. However, the strategic consequences of switching costs are much more complex than the literature assumes when one take into account both the dynamic of the markets and the fact that different consumers have different switching costs.

This op-ed, written in French, describes Google and Doubleclick’s plans to merge.
Policy makers should take a close look at the merger of firms involved in internet advertising because of its consequences for competition and policy.
